The Real Causes of Constant Phlegm and Mucus in Throat and How to Get Rid of It

What’s happening: Stomach acid creeps up into the throat (not the esophagus), irritating mucus glands.

Unlike GERD, you may not feel heartburn—just phlegm, hoarseness, or a lump-in-throat sensation.

✅ What to do:

Avoid trigger foods: coffee, chocolate, citrus, fatty foods, alcohol

Don’t eat within 3 hours of bedtime

Elevate the head of your bed 6–8 inches

Try alginates (like Gaviscon) or see a doctor for PPIs if persistent

3. Food Sensitivities (Especially Dairy)

What’s happening: For some people, dairy (milk, cheese, ice cream) thickens existing mucus—it doesn’t cause mucus, but makes it harder to clear.

✅ What to do:

Eliminate dairy for 2–3 weeks—see if phlegm improves

Replace with oat, almond, or soy milk (unsweetened)

Note: This affects only some people—don’t assume it’s you without testing

Air pollution, strong perfumes, cleaning chemicals

Dry indoor air (especially in winter)
